Digital Engraving Halftone Screen Algorithm Design

Digital sculpting has significant research value due to its effective resolution of issues in traditional manual carving, such as high requirements for carving master skills, intense labor, lengthy duration, and difficulty in compensating for carving errors. In this paper, a new algorithm is designed to convert depth images into line images, and through the processing and optimization of high-quality depth images, digital engraving images with chiaroscuro, geometric features and three-dimensional sense are generated. Precise rendering of surface effects on objects is achieved by adjusting line density and thickness, considering different combinations of angles.
